The first of the examples above restores the break-rewrite state to one in
which terms are printed in full. The second sets the print-level to 3 and
the print-length to 4, to replace substructures deeper than 3 by ``#'' and
those longer than 4 by ``...''; see see ld-evisc-tuple for information about
the shape of the argument of this macro, which is evaluated.

This macro can be executed either inside a break from break-rewrite, or at
the top level. Its effect will persist, except potentially when you execute
``#.'' to exit break-rewrite.
